15. Reflection Eternal f/ Jay Electronica, J. Cole & Mos Def "Just Begun" (3rd Verse)
Best Line: "Couple years ago the game had they pajamas on/But now they on my dick, man I should throw a condom on/Ay, 'cause a nigga coming raw like I ain't got one on."
Album: Revolutions per Minute
Cole's June 18 showdown with Kanye isn't the first time he's gone head-to-head with a legend. On this highlight from Reflection Eternal's comeback album, Cole trades bars with Kweli, Mos Def, and Jay Electronica (back when he still bothered to rhyme). Elec steals the show, but Cole still hits you over the head with a series of dizzying, interconnected rhyme schemes. At one moment he's comparing himself to a "bezel without a flaw," the next he's upgrading himself from Pau Gasol to Lebron.
